    I'd like to see a picture of one of those diaphragm carbs, the only cv style carbs I've seen on a bomber had vacuum pistons. Never any mention of it in magazine articles, back in the day. As far as power was concerned, it certainly was quicker than anything else we had in the shop back then. As far as handling, it didn't feel as light and nimble as a Triumph twin but once you got used to it you didn't notice the difference.

    ^^^agreed - I'm not a Bomber expert by any stretch, but I've never seen any 450 that had carbs with diaphragms

    Looking at the pics, this will be a little work. Cool rare find!

    Can say I am almost 100% certain that front fender does not go on this bike. Looks like a superhawk fender.

    As far a carbs with diaphragms. I think maybe someone is confused between this and the 305.

    As I recall, they had that style front fender. The 305s never used cv carbs, the CB350 (far as I know)was the first. Back in the day we used to put the Honda 450 carbs on two-stroke race bikes. The Bultaco pursang and Greeves engines in the 250 class had big honkin' Amal carbs. Their piston port engines had a real peaky power band and if you came out of a slow corner and opened the throttle too much it would flood the engine and bog down. With the Honda carb you could whack the throttle wide open it would just accelerate, with the slide opening as the engine needed it. The Bultaco rep came to visit our shop one day and the boss showed him the new carb setup. Cranked up the motorcycle,warmed it just a bit, a minute later it sat there and idled on its own. Rode it a couple of laps around the parking lot and pulled up the back door, it sat there and idled. Laid it over on its side(try that with an Amal Monoblock), it lay there on the ground and idled. He sent the guy off with a carb and manifold to try out. A few months later the factory sent it back,they had rejected it,"no increase performance". That figures, at least the damn thing would run all day and not flood every time you looked at it.

    The following info may be helpful.

    The first mention here in the UK of Red Dragon was when the 450s were first being introduced in early 66. Most dealers offered it on black. It wasn't known as the Black Bomber then.

    One dealer only knowing a red version was available advertised it as the Red Dragon. Maybe just to be different.

    There are paint manufacturers that can match up the paint colours exactly given the original will have probably faded by know.

    The silver was Honda Cloud Silver and every now and then a tin or two pops up but rarely.

    The closest colour Red I have found is Ford Sunset Red. This red, like the original, has the knack of looking orangey
    In different lights as it should.

    As mentioned before the frame is a 1965.

    It would be worth checking your harness to see if it has 1965 stamped on it. If it is later then you need to find a 1965 to put on to be correct. They are about.

    I recently found one for my early 1965 360 degree Japanese Home Market bomber I am presently restoring.

    Again the engine number would be useful to see if that is correct. You gave a frame number I do not recognise and wonder if that was a vin no.

    Ray: Engine number CB450E 1009327. I checked the wiring harness and it says 1965. I have been bringing Bmw motorcycles back to life for the past 30 years although I did work on some 1960-1970 Hondas back in the 1990s. -this Honda is an interesting fix. We are only cleaning it up and repairing what is needed, first using used parts then if we have to OEM. The tank is in good condition and the paint good. The frame has some rust in spots. We are not repainting or using new nuts and bolts except where we have to. thank you for you response-Jim

    I realize you are most interested in communicating with Ray on these bikes, he is an expert. However it is worth mentioning that I have a Black Bomber titled as a 1966 with an engine number CB450E-1009144. I believe it to be original to the bike as the frame serial number on mine is close to 1011100. From what I have seen on other K0 450 engines and frames it is typical for the numbers to be about 2000 apart. I would not be surprised if the engine on yours is not the original. Still an early frame though and a great bike to rehabilitate. It will be interesting to get Ray’s take on the numbers.

    Look at the fender stays. Bomber stays are rounded on top, not flat. Plus missing holes on the fender for the cables.

    I agree. It looks like a superhawk front fender on it in the photos
